Blastoconidia are spores formed by budding

• A. Fragmentation
• B. Asexual fission
• C. Budding
• D. Sexual reproduction

Answer: (C)

The key idea here is how blastoconidia form. In yeasts, many asexual spores are produced by budding, where a small outgrowth emerges from the parent cell, nuclei divide by mitosis, and cytoplasm is apportioned to create a new daughter cell. The bud grows and can detach or remain attached to form chains, producing blastoconidia. This budding process distinguishes blastoconidia from fragmentation (where hyphae break into pieces that can grow independently) and from asexual fission (binary splitting typical of bacteria, not yeast spores). Sexual reproduction involves fusion and genetic recombination, not the formation of spores by budding. Because blastoconidia arise specifically through budding, this option best fits the description.
